Doing strenuous exercise, such as warming up before running, on the one hand, is to improve the heart rate and avoid the sudden increase of heart pressure caused by the sudden transition of the body from a quiet state to a moving state. On the other hand, opening the joint ligament can also avoid accidental injuries to ankle joints and other parts during running.

The way to improve, I have a month's experience, I can run 1000 meters every morning or evening, and there is absolutely no problem during the exam.

Running and exercising in the morning can increase vital capacity, while exercising at night can enhance muscle toughness and strength.

Why do you warm up before strenuous exercise?

Muscle is sticky, which will hinder muscle contraction. Viscosity is closely related to temperature. When the body temperature is low, the viscosity of skeletal muscle is high, and when the body temperature is high, the viscosity of skeletal muscle is reduced. Therefore, warm-up activities can increase body temperature, thus reducing the viscosity of skeletal muscle and preventing skeletal muscle strain, which is especially important for winter sports. At the same time, warm-up exercise can also "excite" cardiopulmonary function and improve the working ability of the heart and respiratory system.

Why do you warm up before exercise?

It is absolutely necessary. You should fully warm up before exercise.

Otherwise, it is easy to strain and cramp = =

Especially when swimming in the pool, it is very dangerous to cramp in the water if you don't warm up well.

Why do you warm up before going to physical education class?

By doing warm-up exercises to warm up the whole body, the body can achieve the following effects:

1 increase body temperature.

The increase of body temperature will increase the elasticity and flexibility of muscles, tendons and ligaments, and reduce the possibility of muscle injury.

Prepare the cardiovascular system for exercise.

Proper warm-up exercise makes the heart, lungs and blood vessels of human body gradually adapt to the state of exercise. If there is no warm-up exercise, it will be difficult for the body to adapt to the requirements of formal exercise, and people will feel short of breath and tired. This is also in line with the principle that the amount of exercise should be gradual.

3 increase the blood flow of muscles.

In this way, the more blood flows to the muscle, the more oxygen and glucose the muscle needs to produce energy.

Increase blood flow to the heart.

The more blood supply to the heart, the more helpful it is to prevent cardiovascular problems.

5 improve muscle flexibility

Make muscles more elastic and exercise more flexible.

6 enhance the ability of nerve transmission

With the increase of cardiovascular system activity and blood volume, the coordination between nerves and muscles will also be enhanced, which means that the reaction is more rapid and agile during exercise.

7 Improve the absorption and utilization rate of oxygen.

Due to the increase of body temperature, muscles can better promote the decomposition of oxygenated hemoglobin, release oxygen for muscles to burn fat conveniently to generate energy and provide human exercise needs.

How to warm up before exercise? 5 points

It takes about 3 minutes for the body to realize how much blood it needs to deliver to the muscles. Warm-up exercise should last about 5- 10 minutes, and should be accompanied by stretching activities of major muscle groups. In order to ensure safety, it is generally necessary to do a warm-up exercise before fitness exercise. The main purpose of warm-up exercise is to speed up the heartbeat slightly. It has two advantages: ① it can raise the body temperature of the main parts of the body; ② It can make more blood (oxygen) flow to muscles, so as to prepare the body for more vigorous activities; Stretching after light activity can make tendons more flexible, because it can raise body temperature and increase joint range of motion, thus avoiding joint, ligament and muscle injuries. 3. Which muscles need to be warmed up? Warm-up exercises should focus on large muscle groups, and practitioners can warm up their legs by standing, turning around and blowing knees. If it is chest and shoulders, you can turn around, raise your arms and turn around. People who like treadmills or skipping rope can do brisk walking for 3-5 minutes and some stretching exercises first. 4. Why do you want to relax? In fitness class, it is very important to recover slowly when you have reached and maintained a certain exercise heart rate. Relaxation has two main purposes: ① It can slow down the high-speed beating frequency of pulse. (2) It can make a large amount of blood return to the heart and prevent it from staying in the legs. If you stop exercising suddenly, it will usually lead to dizziness, nausea and fatigue, which are common symptoms when you relax abnormally. 5. Relaxation duration It takes about 3 minutes for the body to realize that it no longer needs to supply more blood to the muscles. Safe relaxation time is at least 3 minutes, and 4-5 minutes is certainly better. All relaxation activities should include muscles and nerves, so as to avoid muscle soreness and tension. There are some fitness tips on excited net.

Does it matter if you don't warm up before exercise?

In order to save time, many people go straight into high-intensity aerobic training without warming up. If so, because the cardiovascular system and lungs have not yet entered the state, the body temperature is relatively low, and the flexibility of muscles is not good, which is easy to cause injuries. Besides, after warming up, you will feel better and exercise longer. In other words, if you exercise without warming up, you will get tired more easily.

How to warm up before running?

The warm-up before running is that leg press turns his ankle and wrist, then bends his waist deeply and does several squats.

Don't run too fast at first, try to run slowly, and then speed up a gradual process.

I hope to adopt.

Why do you have to warm up before exercise?

Why do you warm up before exercise?

Reason:

1 to avoid pulling the ligament. When the body is in a quiet state, ligaments are mostly in a relaxed state. Various actions of stretching ligaments during warm-up can make ligaments stretch and be in a tense state, which can avoid many injuries.

2. Increase the joint fluid in the joint capsule. When the joint capsule is heated, it will produce a lot of joint fluid. Synovial fluid is called synovial fluid, which can reduce the friction between articular surfaces, so it is not easy for us to damage articular surfaces during strenuous exercise.

3. Make the sports center more active. After warm-up, the human brain will make various complicated adjustments to keep the body in an exciting state of exercise.

Therefore, warm-up exercises must be done before exercise!

Why do you need to warm up before exercise?

In order to prevent injuries in sports, minor injuries usually involve strains, cramps, muscle tears and the like at most, while major injuries may be fatal.

Why is it better to warm up before exercise?
